The 68140 4" (10 cm) pipe cleaning attachment features a durable polypropylene body friction fitting to standard 1.5” (38 mm) male friction wand or handle connections. The offset wand connection permits the tool to reach over pipes up to four inches in diameter without the wand interference reducing surface contact of the nylon brush. The offset neck also works to ensure a stable connection between the pipe cleaning attachment and standard wand connections. The generous nylon brush is 0.375” (10 mm) in length providing for effective brushing against dirt and dust which has adhered to the pipe or conduit surface. The 68140 is a 4” (100 mm) curved pipe and conduit cleaning tool designed to female fit to industry standard 1.5” (38 mm) friction extension wands. A 30 degree angle is designed into the tool to position the four inch curved surface to fit over the pipe or conduit for optimum cleaning effectiveness. A stiff durable nylon brush is centered in the channel designed to allow airflow on both sides of the brush for effective source capture of the dust and debris released as the tool moves over the surface of the pipe.
